Search Results: is she trying to string me along

I don't really understand why when a girl hears a guy likes her she decides to go and tell everyone.

So yesterday, my friend (without my consult) decided to tell my other friend (who's a girl) I like her. She was shocked, but she didn't say no to me. Now today, she confronted me, and asked me if it was true. I said "I don't know," and she tells me to tell her when I do know. But the thing is, it seems every person she comes in contact with she feels the need to tell them. My friend today heard her telling her crowd of friends about me and how I was like "I don't know." It kind of made me feel like I was being made fun of. But the thing is, last month I told her I liked a different girl and she just began to ignore me for no reason. But she keeps telling me she doesn't know how she feels, yet she goes to her group of friends and keeps telling them about our conversations. It kind of feels like if I told her "yes," she'd go tell me she was lying and she'd go to her friends and make fun of me. But since she heard, she seems more open to me and seems to have began teasing me a little more, and she seems to have began playfully poking me. But as of right now, her actions seem to contradict, which is what I'm having difficulty deciphering. Is she making fun of me and trying to string me along, even though we're friends? Or is she not? Am I fuel for her group of friends?

Her personality:
- Extroverted
- Tons of friends
- Friendly (impossible to tell if she likes you) to every boy
- Social
- Funny

Me on the otherhand, LOL:
- Introverted
- Not many friends (maybe 4)
- Not exactly the most friendly person (know me over time, I am)
- Not very social
- Not even a bit funny.
